What can I do?** A: As of 5/2023, master lock says you are out of luck if one shows up and the preset code doesn’t open the lock. I ordered this lock - code doesn’t work (I have a few of these, it’s not operator error), called master lock. They say they can’t help. **Q: How many digits are in the combination?** A: 4 digits **Q: Can anyone confirm that the numbers do not spin if unlocked, but show the combination? This is a huge security flaw on job sites where it will be left** A: I DISAGREE with the two other posters. I just had one delivered yesterday (8/13/19) and am returning it because, among other problems, once it's unlocked, you CANNOT rotate the numbers unless you return the shackle to the locked position. If you leave the shackle open, the correct combination is there for anyone to see. **Q: Is it possible to get a replacement rubber cover for the lock? It was delivered with that part missing.** A: Don't bother. It'll fall off within days or hours. The rubber part holding it to the lock is very flimsy and flexible, so it won't stay on. You'd have to super glue it. Horrible design. And the lock can be defeated in 30 seconds WITHOUT any tools. Someone can identify your combination numbers in 30 seconds or less even if you scramble them. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use, durable, sturdy. *by A***E on 29 September 2024* High quality production.

It's quite chunky and feels like it's going to take some effort to cut through, so it gives a positive feeling as a reliable lock. The combination was easy to change, and therefore so far so good! ## Frequently Bought Together - Master Lock Combination Lock, Heavy Duty Weatherproof Padlock, Resettable For Outdoor Use, Brass Finish, M175XDLF - Lumintrail 12mm (1/2 inch) Heavy-Duty Security Cable, Vinyl Coated Braided Steel with Sealed Looped Ends (4', 7', 10', 15' or 30') (4-FT) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/148418289-master-lock-m175xdlf-heavy-duty-outdoor-combination-lock-brass-finish](https://www.desertcart.us/products/148418289-master-lock-m175xdlf-heavy-duty-outdoor-combination-lock-brass-finish) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
